Since the 328 stock piping is 75mm(2.95 inches I believe), do guys you know if a 3inch exhaust clamp will work?

Depends on the type of clamp you're trying to use. Do you have a picture of it?

Either way, I'd go with the OEM clamp if you want to make sure you don't have an exhaust leak. I think I got mine brand new for $60.

Thanks for the input TurboM, exactly what I want to avoid as well. Where did you happen to buy the Oem clamp?

I doubt that will seal but you can always give it a shot. I purchased this one:
